Derrick Lyman, 24, was found in the first-floor hallway of the apartment building at 2103 Park Hill Drive at 6:20 p.m., police said.

Neighbors said they and the apartment security person performed CPR on Lyman while they waited for paramedics to arrive. They were frustrated that someone put them in this position and wished they could revive their friend, they said.

"One person can only do CPR for so long, and that's why it took three of us, taking turns with positions," said Yugonda Akrie, a friend of the victim. "That’s not right, and we’re emotional because we know him."

Lyman was taken to UPMC Presbyterian, where he was pronounced dead.

His friends were upset with the violence, which happened just a few blocks from where 15-month-old baby Marcus White was killed by gunfire two months ago.

"I watched this baby (Lyman) grow up, from the time he was 2. Somebody's baby is dead," said Laura Duncan, a friend of the victim. "The code is gone. Say something if you’ve seen something, what happened. Say something."

There are no suspects in either case. Witnesses said an African-American man wearing a gray hooded sweatshirt and khaki shorts was seen fleeing Wednesday night's shooting.

Detectives said the shooters did not appear to care that there were children playing outside just feet away.

"No, they don't, the actors don't care who's in the way of the bullets, they don't," said Lt. Dan Herrmann, of the Pittsburgh police.

Anyone with information is asked to call homicide detectives at 412-323-7161.
